Hi Sebastian,

here are examples with ggplot2 and basic graphic.

You may also impress your audience by using iterative graphs as provided by dygraphs package.

https://blog.rstudio.org/2015/04/14/interactive-time-series-with-dygraphs/

You have to convert your xts objects starting from your ts ones.

An example:

getSymbols("AAPL", src = "yahoo", from = as.Date("2013-07-01"), to = as.Date("2016-06-30"))
getSymbols("YHOO", src = "yahoo", from = as.Date("2013-07-01"), to = as.Date("2016-06-30"))
getSymbols("CPHD", src = "yahoo", from = as.Date("2013-07-01"), to = as.Date("2016-06-30"))
getSymbols("EMC", src = "yahoo", from = as.Date("2013-07-01"), to = as.Date("2016-06-30"))
AAPL.xts <- Ad(AAPL)
YHOO.xts <- Ad(YHOO)
CPHD.xts <- Ad(CPHD)
EMC.xts <- Ad(EMC)

df <- data.frame(AAPL.xts, YHOO.xts, CPHD.xts, EMC.xts)
head(df)

library(dygraphs)
dygraph(df)

Best,
